ELECTROMAGNETIC INTERFERENCE
When the machine is operating close to a source of high electromagnetic interference, such as a radar station,
some abnormal phenomena may be observed.
• The display on the monitor panel may behave erratically.
• The warning buzzer may sound.
These effects do not signify a malfunction and the machine will return to normal as soon as the source of inter-
ference is removed.
DO NOT GET CAUGHT IN WORK EQUIPMENT
The clearance in the area around the work equipment changes according to the movement of the link. If you are
caught, this may lead to serious personal injury or death. Do not allow anyone near any of the rotating or tele-
scopic parts.
PRECAUTIONS RELATED TO PROTECTIVE STRUCTURES
The operator's compartment is equipped with a structure (such as ROPS, OPG) to protect the operator by ab-
sorbing the impact energy.
As for the machine equipped with ROPS, if the machine weight
(mass) exceeds the certified value (shown on ROLL-OVER
PROTECTIVE STRUCTURE (ROPS) CERTIFICATION plate),
ROPS will not be able to fulfill its function. Do not increase ma-
chine weight beyond the certified value by modifying the ma-
chine or by installing attachments to the machine.
Also, if the function of the protective equipment is impeded, the
protective equipment will not be able to protect the operator,
and the operator may suffer injury. Always observe the follow-
ing.
• If the machine is equipped with a protective structure, do
not remove the protective structure and perform operations without it.
• If the protective structure is welded, or holes are drilled in it, or it is modified in any other way, its strength
may drop. Any modification is prohibited.
• If the protective structure is damaged or deformed by falling objects or by rolling over, its strength will be
reduced and it will not be able to fulfill its function properly. In such cases, always consult your Komatsu
distributor.
• Even if the protective structure is installed, always fasten your seat belt properly when operating the ma-
chine. If you do not fasten your seatbelt properly, it cannot display its effect.
Always fasten your seat belt while operating the machine.
